For the purpose of this study was to determine the growth of Candide albicans on the surface of the resilient denture liners. The discs$(40\times40mm)$ of 2 resilient lining materals (Molloplast B, Mollosil) and one conventional acrylic resin (K-33) and one metal plate were processed and disinfected. Firstly, the test discs were placed into petri dish, and Candide albicans suspensions was overlayed on the test discs. And the test discs were incubated with intermitant shaking for 1 hour, 2 hours, 6 hours, 12 hours, 24 hours. After incubation, imprint culture method was achived and counted the colony on the agar plate. Secondly, the effect of denture cleansing agents on the growth of Candide alibicans on the resilient dentureliners was evaluated. The results were as follows : 1. The growth of Candida albicans on discs of Molloplast B and Mollosil was increased than that on discs of acrylic resin and metal plate (p<0.05). 2. As Candide albicans suspensions were incubated for 2 hours, the growth of Candida albicans on discs of Mollosil was increased than that on discs of Molloplast B (p<0.05), and the growth of Candide albicans on discs of metal plate was increased than that on discs of acrylic resin (p<0.05). 3. As Candide albicans suspensions were incubated for 6 hours, the growth of Candide albicans on discs of Mollosil was increased than that on discs of Molloplast B (p<0.05). 4. The growth of Candide albicans on discs of Mollosil and Molloplast B in treating denture cleansing agent was inhibited than control discs (p<0.05).

Background and Objectives: TThe prevalence of subclinical hypothyroidism and mean serum TSH are known to increase with aging. The large study on the prevalence of subclinical hypothyroidism and the TSH distribution in Korean has been very rare. The aims of the present study are to investigate the prevalence of subclinical hypothyroidism in Korean and to determine whether the change of the TSH distribution with aging might account for the increasing prevalence of subclinical hypothyroidism with aging. Materials and Methods: We measured serum TSH, total T3 and T4 in 27,173 subjects for general medical examination in 2005 and all of them were free of thyroid disease. The distribution of TSH with aging was analyzed. Results: The prevalence of subclinical hypothyroidism was 10.1% and it increased with aging. Subclinical hypothyroidism was more common in women than in men. Mean, median and 97.5 tile of serum TSH were 2.03 mIU/L, 2.08 mIU/L and 7.03 mIU/L respectively. They increased progressively with aging. Conclusion: Higher prevalence of sublincial hypothyroidism in the elderly might result from the shift of TSH toward higher concentration with aging.
